They are continually forcing me to reset my password also. It's becoming a real pain in the (where you sit down)!
Judging by the lack of response you've received, I doubt anybody from Comcast ever visits these forums.
I may have to dump my Comcast email account and set up a Gmail or Yahoo account. Unfortunately, i'ts a big inconvience to give all my friends a new email to contact me at.
What else can we do? I can't just keep reseteing passwords every time I want to check my email!
I am sending you both PMs to provide info on why they are being reset.
